This is now sold out on the MAC website. First off, the packaging, while tacky, is larger than the normal Rapidblack Penultimate liner. In fact, it looks and feels just like a children's black marker. The application would be the same as applying with an ultrafine Sharpie, but that's kind of what I didn't like about it. The performance is the same as the regular (reformulated late last yr I guess?) Penultimate Eye Liner, which I do like, but it just felt wrong in this big size. :\
